An industrial chiller is an expensive piece of machinery. Additionally, it is a large part of the operation costs of any kind of organizations. For many of these organizations, the chiller is actually the single biggest user of energy. For this reason, it is hugely important to properly maintain and service is, to allow it to be as efficient as possible.
Luckily, there are many really good chiller service companies you can turn to if something does go wrong. Additionally, most chillers have improved in quality in terms of their unit design, refrigerants and controls. However, this does not mean you should be flippant about the maintenance of your device. The following hints and tips can help you to make sure that they remain properly functioning and efficient.
1 – Use the Operating Log
All chillers should have their performance documented each day. You should also compare these logs regularly to see whether a problem is starting to develop. When you keep a log, you can also keep track of existing conditions and identify whether there are trends.
2 – Get a Leak-Free Unit
One of the main reasons why chillers don’t perform as well as they should is because they are leaking. If there is a leak, moisture and air can seep into the device and get trapped inside of the condenser. This can seriously reduce the overall efficiency and capacity of the cooler. Moisture can lead to the development of acids that corrode the bearing parts and motor, as well as causing rust in tubes.
3 – Keep the Tubes Clean
The chiller heat transfer must work as efficiently of possible. If it can’t do that, the overall performance of the device is reduced. If the evaporator tubes and the condenser is kept clean, then heat can be transferred effectively at all times. Yes, it is a lot of work to do this, but it is absolutely necessary to ensure good performance.
4 – Always Maintain the Water Treatment
To transfer the heat efficiently, chillers use water. This means that it should be properly treated so that there are no issues with corrosions, scaling or biological growths. If the water system is closed, it only needs one chemical treatment. If, however, it is an open system, you will need regular and continuous chemical treatment. Make sure you consult with an independent expert in order to identity the right type of water treatment for your chiller.
5 – Analyze the Oil and Refrigerant
Finally, in order to make sure your chiller is well-conditioned and efficient, you should chemically analyze the refrigerant and the oil. You should do this every year so that any contamination issues are identified before they cause any significant issues. The analysis will look at things such as unwanted air, moisture, acids, metals and other types of contaminants. Very often, the manufacturer of your chiller can offer you a yearly analysis of the refrigerant and the oil, which you should take advantage of if you can.
